Specification of Letters Patent. I Application filed February 26, 1906' Serial No. 303,032-

Patented Sept. 4:, 1906.

Figure 1 is a'vertical sectional view of an ice-cream freezer provided with my improved gearing. Fig. 2 is a perspective View showing the supporting-ring detached from the cross-bar; Fig. 3, a vertical central lon-' gitudinal section through a portion of the cross-bar supporting the gearing, and Fig.4

ahorizontal section on the line 4 4 of Fig. 3.

The object of this invention is to rovide a simple, strong, and easily repaire and inspected gearing for that class of freezers known as ftriple-motion? freezers; and .to the accomplishment of this object and such others as may hereinafter a pear the inven tion consists of the arts and combination of parts hereinafter fu ly described, and particularly pointed out in the appended claim, reference being had to the accom anying drawin s, forming a part of this specification, in whic i the same reference characters designateilike parts throughout the several views.

Referring to the drawings annexed by reference characters, G represents the tub, K the can which incloses the beater-shaft J, carrying the boaters j and the scraper-frame h, carrying the usual scrapers'h, the upper tubular head H of the scraper-frame extendingup through an openingk in the candzo The upper end of t e beater-shaft exten s up throu h the tubular head H and is providedwit an angular shank-at its extreme upper end, while the head H is also provided with an angular shank c The cross-bar supporting the gearing coni sists, as usual, of the semitubular parts a and e and the central dome-like part A, and this cross-bar is removably fastened in place on top of the tub at one end by the usual lug g and 6311111 and at the other end by the usual legs a, engaging in the usual eyes g", fastened to the tub. The operating-crank d. is attached to the end of the driving-shaft d, which extends inwardly into the dome and carries the driving bevel-pinion D.

1 Fastened to the cross-bar by means of lat eral carat and suitable screws, which are eing passed up through the ears into the cross-b ar, is a splash ring or guard B, which depends a suitable distance'to serve as a guard to prevent brineor ice being thrown up into the gearing. Formed integral with this depending' ring is a series of three radial wings I), which incline upwardly into the dome and which are connected at their upper ends by a vertical tubular bearing b whose interior ta pers upwardly. Fittin up into this bearing 1) is a tubular shaft c of t e lower gear-wheelO, the upper side of this wheel bearing against the lower end of thebearing b Extending up through the tubular shaft 0 is a shaft F, which has attached to its upper endlf the u per bevel-gear E, which .gear rests upon the u per end of the tubular bearing b This w fieel E is formed with an uper tubular extension e, through which an the upper end F of the shaft the transverse fastening-pin is passed. The shaft F is provided with an ann'ularshoulder, which engages an inwardlyextendin shoulder a on the tubular shaft 0 and in t at manner holds said tubular shaft in place. The lower end of shaft Fis provided with a socket f 2 for engagement with the shank of the beater-shaft, and the lower end of the tubular shaft is provided with asocket c for engagement with the shank of the scraper-shaft, in the usual manner. Y

The usual frainek is fastened to the bottom of the can and rovided with the de' ending in s W, whic serve as supportinge swhen t e can isremoved from the tu T e frame It" is provided with a depending central pivot, whichhas its bearing in a socket L, fastened to the bottom of the tub. The lower squared end of the' beater-shaft fits in a squared socket hfiforrned in the bot tom of the can in the usual way. It will be observed that the rotation of the drive-shat continuously in one direction serves to rotate the beater-shaftand the scrapers in opposite direct ons, the can being rotated with the beater-shaft, thereby obtaining the socalled triple motionf A special feature of the present invention lies in mounting the driven gears in a bearing which may be readily removed from the dome for cleaning and repairin and at the same time afford the gears a steady bearing or support. By extendin the radial supporting-wings upwardly ant inwardly the greatest possible strength is oburable and tained with a minimum of metal, and the de- -as a splash-guard to the gears.

pending supportingring not only provides 0r readily removing the gears, but also serves @porting the gears by an independent ring supported below the cross-bar enables the ring to be attached to the bar with the greatest degree of rigidity, since the lateral fasten- 'ing'lugs or ears may be located directly ofpposite each other in the vertical plane 0 the cross-bar, which enables them to be made as heavy and as long as the size of the inachine I .may require, as is obvious. This manner of mount ng the driven gears is especially advantageous' in the larger sizes of freezers, as

in these larger-sizes the gearing is subjected to great strain when the cream becomes har What I claim, and desire to secure by Let- -ters Patent, -is Y In an 1cecreainfreezergearing,-the combination of asngpogting-bar provided with a dome, a dnm 'journaled in' this cross:

bar and carrying a driving bevel-pinion; -a depending annular splash uard removably fastened to the under side 0 the bar and provided with a series of radial wings extending upwardly into the dome and connected to a vertical tubular bearing, a tubular shaft extending up into this bearing and carrying. a

bevel-gear and an an ular socket at its lower 3 ln testimony whereoil hereunto aflix my signature, in the presence of two witnesses, this 24th day of February, 1906.;
